Add Yesod detection and route analysis for Haskell projects

[Copilot]

Yesod projects were not recognized or analyzed, so Noir missed endpoints declared through Yesod’s routing DSL. This adds first-class support for detecting Yesod apps and extracting routes from both inline and file-based route definitions.

• Framework support

  • adds haskell_yesod tech metadata and wires Yesod into detector/analyzer registration
  • recognizes Yesod projects from Haskell source usage (mkYesod, parseRoutes, parseRoutesFile, import Yesod) and package metadata (package.yaml, .cabal)

• Route extraction

  • parses inline Yesod route blocks:
    • mkYesod ... [parseRoutes| ... |]
    • mkYesodData ... [parseRoutes| ... |]
  • parses external route files referenced via parseRoutesFile
  • supports nested route trees, multiple HTTP methods per route, and comment/line-continuation handling

• Path parameter handling

  • converts Yesod dynamic segments into Noir path params:
    • #Type → :type
    • *Type / +Type → wildcard path params
  • preserves parameter type information in extracted params for dynamic and multipiece segments

• Coverage

  • adds unit coverage for Yesod detection
  • adds functional fixtures/specs covering:
    • inline routes
    • external .yesodroutes files
    • nested route groups
    • single and multi-piece dynamic segments

Example of routes now recognized:

mkYesodData "App" [parseRoutes|
/ HomeR GET
/blog/#Text BlogPostR GET POST
/api ApiR:
    /health HealthR GET
    /users/#UserId UserR PUT DELETE
|]

This produces endpoints such as:

• GET /
• GET /blog/:text
• POST /blog/:text
• GET /api/health
• PUT /api/users/:user_id
• DELETE /api/users/:user_id

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• www.yesodweb.com
  • Triggering command: /home/REDACTED/work/_temp/ghcca-node/node/bin/node /home/REDACTED/work/_temp/ghcca-node/node/bin/node --enable-source-maps /home/REDACTED/work/_temp/copilot-developer-action-main/dist/index.js (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
